DNA's stuff isn't visual, it isn't character. It's the words. Losing the pan-galactic gargle blaster is an example of the hollywoodification of the book.
And Red Dwarf turned to crap after the first couple of series, because the strong characterisation (Lister the slob, Rimmer the snob, Cat the selfish, Kryten the subservient) was diluted.
And the American version? Heaven help us, that was AWFUL from day 1.
To be honest, I wish the film-makers would stop trying to bring this sort of thing to the big screen. Write something original, ferfook's sake.
The Matrix worked. <-- clue to Hollywood.
